Deon Burton sparked wild celebrations at Hillsborough as Sheffield Wednesday's 4-1 win over Norwich secured their Championship survival.
Burton ghosted in to head home Tommy Spurr's fine cross to give the Owls a two-goal advantage with 15 minutes remaining.
The Wednesday striker had held his nerve to convert a 21st-minute penalty after Darren Huckerby had slammed home (9) to give the Canaries a flying start.
The Owls, who needed a win to guarantee they stayed up looked much more assured in the second period and after Ben Sahar had eased fraying home nerves with a close-range second (53), Burton's second rendered results elsewhere irrelevant.
Substitute Leon Clarke added a fourth for the home side in the 87th minute, bustling in on Bartosz Slusarski's pass and somehow keeping both his balance and the ball to poke home a fourth.
